Season pork chops with white vinegar, oregano, adobo, and black pepper. Mix well, cover, and marinate for 30–45 minutes or overnight in the refrigerator.
Heat oil in a Dutch oven over medium-high heat. Brown pork chops for about 2 minutes per side, working in batches. Remove and set aside.
Reduce heat slightly. Add onion, garlic, and sofrito. Sauté for 3–4 minutes until softened and fragrant.
Stir in tomato sauce and water. Add pimentos, potatoes, carrots, turmeric, oregano, and sazón (if using). Mix well.
Return pork chops and any remaining marinade to the pot. Bring to a simmer and cook uncovered for 10 minutes.
Taste the broth and add salt if needed.
Cover, reduce heat to medium-low, and simmer for 45 minutes to 1 hour, stirring occasionally. Add a generous bunch of fresh cilantro during the last 7 minutes.
Remove a few tender potatoes, mash them, and stir them back into the sauce.
Serve hot with white or yellow rice.
